Microwave shows E11 and stops when using sensor cooking or auto programs.

Safety first: Unplug the microwave before removing covers.

• Step 1 – Clean cavity: Wipe down the interior, especially near the steam outlet and sensor area (often on the top of the cavity). Remove grease and food splatter that can affect readings.
• Step 2 – Locate sensor: On many AEG models, the humidity sensor is mounted behind a small grille inside the cavity or in the top duct. Access it from the top after removing the outer cover.
• Step 3 – Inspect and clean: Gently clean the sensor surface with a dry cloth or cotton swab. Do not use excessive moisture.
• Step 4 – Check wiring: Ensure the sensor connector is firmly seated on the control PCB and that the harness is undamaged.
• Step 5 – Replace sensor: If E11 persists, replace the humidity sensor module with the correct AEG part. If still unresolved, the control PCB may be defective.
